Guide Bar
• Invert the bar occasionally to avoid a parcial wearing down.
• The bar´s rail always has to be square. Verify the wearing down of the bar´s rail. Place a ruler
next to the bar and to the cutting teeth. If there is separation between them, the rail is normal.
Otherwise the bar´s rail is worn away. This bar has to be fixed or replaced.
